Can anyone explain why in certain circumstances the Teradata parser requires parens around a function call? I have a suspicion that there's an implicit conversion taking place but I don't see why.
select coalesce(null, '123')
select coalesce(null, '123') || 'foo'
select (coalesce(null, '123')) || 'foo'
Ah, the parens make all the difference.
